SEALEVEL 8112
SeaDAC Lite PLC-8 |
|
| |
Control and monitor 4 optically isolated inputs and 4 Form C (SPDT) relay outputs via any USB connection with the 8112. Inputs can range from 5-30VDC, while the high-current Form C relays can switch up to 6A loads at 250VAC and up to 5A at 60VDC. The Form C relays can be wired for either normally open or normally closed operation. Each Form C relay has a discrete common and each pair of inputs share a common. Status LEDs display I/O activity and field wiring is simplified via 3.5mm removable terminal blocks.
The SeaMAX software suite supports the SeaDAC Lite family and is designed to work with third party applications via the SeaMAX API. Sealevel's SeaMAX software drivers and utilities make installation and operation easy using Windows 2000, XP and Vista operating systems.
The 8112 integrates a patent-pending SeaLATCH USB port, which is fully compatible with standard USB cables. When used with the included USB cable with a SeaLATCH USB type B connector, the metal thumbscrew provides a secure connection to the device and prevents accidental cable disconnection.
SeaDAC Lite modules are housed in a rugged, attractive plastic enclosure ideal for mounting on walls, under counters, or inside panels. The 8112 is USB bus powered, so no external power supply is needed. Standard operating temperature range of SeaDAC modules is 0°C to 70°C and extended temperature range (-40°C to +85°C) is optional.
